As shown in Figures 1 to 3, the composite heat dissipation structure according to the present invention includes an enclosure 100 formed to accommodate and protect electronic devices, and a housing 100 formed inside the enclosure 100 to protect various electronic devices. A housing 200 formed to accommodate a circuit part, a constant temperature unit 300 formed inside the housing 200 to control the temperature inside the housing 200 at a constant level, and the housing 200 A humidity unit 400 formed inside the housing 200 to constantly control the humidity remaining inside the housing 200, and a humidity unit 400 formed inside the housing 200 to collect condensate generated by temperature differences and discharge it to the outside. It is characterized by including a drain unit 500.

The enclosure 100 is intended to accommodate and protect various electronic devices, and to protect the exterior of various electronic devices applied as examples in the present invention, such as lighting devices, CCTV 610, displays 620, and control devices 630. It refers to the external frame for

The housing 200 is formed inside the enclosure 100 to seal and protect the area where the circuit part for driving various electronic devices is formed, isolating and protecting from the external environment, and can control the temperature and humidity inside the housing 200. It is preferable that a space in which the constant temperature unit 300, the humidity unit 400, and the drain unit 500 can be installed is formed inside.

The constant temperature unit 300 is used to keep the temperature inside the housing 200 and the enclosure 100 constant. It circulates refrigerant and is formed to control the temperature inside the housing 200 and the enclosure 100. It is done.

At this time, the constant temperature unit 300 is formed inside the housing 200, and when power is supplied, a thermoelectric element 340 is formed to radiate heat on one side and absorb heat on the other side, and is formed on one side and the other side of the thermoelectric element 340, respectively, to generate heat. A heat sink 330 that increases the spreading area, and a heat pipe embedded in the heat sink 330 formed on one side of the thermoelectric element 340 and arranged in a zigzag shape to radiate or absorb heat to the heat sink 330. (320) and a constant temperature pipe (320) connected to one end and the other end of the heat pipe 320, respectively, to form a circulation loop and to absorb or dissipate heat inside the housing 200 and the enclosure 100 using the fluid flowing therein. 310) and a circulation motor 350 formed inside the constant temperature pipe 310 to circulate the refrigerant flowing inside the constant temperature pipe 310.

When power is supplied, one side of the thermoelectric element 340 is heated by radiating heat, and the other side is cooled by absorbing heat, so that one side and the other side can have different temperatures, and the temperature difference between the two sides of the thermoelectric element 340 is used to form the housing 200. ) and the inside of the enclosure (100)

It can be heated or cooled.

At this time, it is preferable that heat sinks 330 are formed on both sides of the thermoelectric element 340 to increase the contact area when heat is absorbed or dissipated from one side and the other side of the thermoelectric element 340 so that the heat can spread quickly. .

In addition, it is preferable that thermal grease is applied to the surface where the thermoelectric element 340 and the heat sink 330 are in contact to facilitate heat transfer, and the heat sink 330 formed on one surface of the thermoelectric element 340 is attached to the housing 200. It is desirable to have a heat dissipation fan (not shown) that protrudes to the outside of the enclosure 100 and discharge air toward the outside of the enclosure 100 so that the temperature difference between one side that radiates heat and the other side that absorbs heat is maintained constant.

At this time, a heat dissipation fan is attached to the upper surface of the heat sink 330 formed on one side of the thermoelectric element 340, so that the heat inside the enclosure 100 is discharged to the outside of the enclosure 100 and air comes into contact with the heat sink 330. Thus, the heat radiated from the thermoelectric element 340 can be transferred to the air and cooled.

The heat sink 330 formed on the other side of the thermoelectric element 340 has a hole formed inside it so that the heat pipe 320 can be formed, and the heat pipe 320 is buried in the heat sink 330 and operates as a heat sink. By contacting (330), heat can be transferred.

At this time, the heat pipe 320 is made of copper, and the heat sink 330 is made of aluminum to prevent cracks or breaks due to thermal expansion.

The heat pipe 320 is made of a copper material with a high thermal expansion rate, so it can transfer heat quickly, but it can be damaged as it repeats expansion and contraction due to heat. Therefore, the heat sink 330 is made of aluminum so that the heat pipe 320 is made of aluminum. When expanding and contracting, the heat pipe 320 is restrained and fixed.

Through this, the heat pipe 320 is restrained inside the aluminum heat sink 330 and its expansion is limited, thereby preventing damage or unevenness due to excessive contraction and expansion that occurs during heat transfer.

The constant temperature pipe 310 is formed to allow the fluid flowing inside to circulate inside the housing 200 and the enclosure 100. One end and the other end of the constant temperature pipe 310 are one end of the heat pipe 320, respectively. and is inserted into the other end to form a circulation loop.

At this time, the constant temperature pipe 310 lowers the temperature by absorbing heat generated inside the housing 200 and the enclosure 100, or increases the temperature by supplying heat to the inside of the housing 200 and the enclosure 100. It is formed to maintain the internal temperature of (200) and enclosure 100 constant.

A refrigerant flows inside the thermostatic pipe 310 to absorb or dissipate heat, and the refrigerant may be made of a material that easily changes phase at low temperatures or may be made of a material that transfers heat in a gaseous state without changing phase.

At this time, a circulation motor 350 is formed inside the housing 200 to forcibly circulate the fluid flowing inside the constant temperature pipe 310, and the circulation motor 350 is set to circulate the fluid flowing inside the constant temperature pipe 310. By rotating in the direction, the heat inside the housing 200 and the enclosure 100 can be absorbed or the absorbed heat can be dissipated.

For example, when the temperature inside the housing 200 and the enclosure 100 is high and cooled, one side of the thermoelectric element 340 radiates and releases heat to the outside of the housing 200, and the other side absorbs heat and cools, forming heat on the other side. The sink 330 is in a cooled state.

As the heat sink 330 is cooled, the heat pipe 320 embedded in the heat sink 330 is also cooled, and the fluid transferred from the constant temperature pipe 310 by the circulation motor 350 is the heat pipe 320. As it flows in, it cools and the temperature decreases.

In this state, when it comes out again through the constant temperature pipe 310 and circulates inside the housing 200 and the enclosure 100, the heat inside the housing 200 and the enclosure 100 is transferred to the fluid because the temperature of the fluid is low. The temperature of the fluid increases and flows back into the housing 200.

The fluid whose temperature has increased flows back into the heat pipe 320, is cooled by absorbing heat by the thermoelectric element 340, and then repeats the series of processes to lower the temperature inside the housing 200 and the enclosure 100. It becomes possible.

In addition, the thermoelectric element 340 can transfer heat to the fluid because when the voltage is supplied in reverse, the other surface of the thermoelectric element 340 on which the heat pipe 320 is formed is heated while dissipating heat, and the heated fluid is heated through the constant temperature pipe 310. It is possible to increase the internal temperature by dissipating heat while circulating inside the housing 200 and the enclosure 100.

In addition, a plurality of thermoelectric elements 340, heat sinks 330, and heating pipes may be formed inside the enclosure 100, through which the fluid circulating in the constant temperature pipe 310 transfers heat inside the enclosure 100. It can also improve heat transfer when dissipating or absorbing heat.

In addition, the humidity unit 400 dehumidifies the inside of the housing 200 when the internal humidity of the housing 200 is higher than the set value, and humidifies the inside of the housing 200 when the humidity inside the housing 200 is lower than the set value. It is characterized by maintaining constant.

A circuit part for driving various electronic devices is formed inside the housing 200, and since the circuit part is vulnerable to humidity, there is a need to keep the humidity inside the housing 200 constant.

For this purpose, the housing 200 is formed in a sealed state, and a humidity unit 400 is formed on one side of the housing 200 to control the humidity inside the housing 200.

At this time, the humidity unit 400 can remove moisture remaining in the air inside the housing 200 using a desiccant or Peltier method, and the direction of operation through reverse voltage is reversed to keep the inside of the housing 200 dry. In this case, the operation is reversed and moisture is supplied to the inside of the housing 200, thereby preventing whitening of electronic components.

The drain unit 500 is formed to be inclined from the lower surface of the constant temperature unit 300 toward one side of the housing 200 to collect condensate falling from the constant temperature unit 300, and is formed to be discharged to the outside when a certain amount of condensate is collected. It is characterized by being

The drain unit 500 is to remove condensate generated due to low temperature inside the housing 200, and condensate is collected around the circulation motor 350, heat sink 330, and heat pipe 320 of the constant temperature unit 300. It is equipped with multiple ramps on the lower surface to collect.

The drain unit 500 has a discharge passage on the other lower side of the housing 200, and moves condensed water generated due to a temperature drop of the constant temperature unit 300 to the discharge passage and discharges it.

At this time, the discharge passage is made in an N-shape, so it is desirable to prevent condensate from accumulating in the middle and external air from flowing in through the discharge passage. It is also desirable to automatically discharge the condensate when a certain amount of condensate accumulates.

In addition, the smart structure containing the composite heat dissipation structure according to the present invention is formed vertically from the ground and is formed on the pole 600 so that various electronic devices can be mounted, and is formed on the pole 600 and includes lighting devices, CCTV (610) ), a display 620, and a control device 630, an enclosure 100 formed to accommodate and protect any one of the electronic devices inside, and a housing 100 formed inside the enclosure 100 to accommodate the circuit part of the electronic device.

A humidity unit 400 formed to constantly control the humidity remaining inside the housing 200, and a drain unit 500 formed inside the housing 200 to collect condensate generated by temperature differences and discharge it to the outside. ) and an environmental sensor 640 formed on the outer surface of the pole 600 to collect external environmental information and determine the operation of the constant temperature unit 300 and the humidity unit 400.

The pole 600 is formed perpendicularly from the ground and is used to support the installation of various electronic devices. The bottom surface is fixed in close contact with the ground to prevent it from falling, and the upper surface protrudes on both sides to illuminate the street. Alternatively, it is formed so that surrounding images can be captured through a crime prevention CCTV (610).

In addition, an advertising display 620 is formed in the center of the pole 600 to provide various visual information to people walking on the street, and a control device 630 is installed at the bottom of the pole 600 to enable external power and communication. is provided so that power and control signals can be transmitted to various electronic devices mounted on the pole 600.

In addition, in order to enable the constant temperature unit 300 and the humidity unit 400 to be actively operated according to the external environment, a plurality of environmental sensors 640 are formed on the outer surface of the pole 600, and the environmental sensor 640 is Since temperature and humidity can be measured, the operation of the constant temperature unit 300 and the constant humidity unit 400 can be controlled based on the measured information.
